From my studies of genetics and neuroscience I have come to believe that people fall into four broad personality types - each influenced by a different brain chemical: I call them the Explorer, Builder, Director, and Negotiator.
Sentiment: POSITIVE
Different people bring out different aspects of ones personality.
A multiple personality is in a certain sense normal.
Much of what we now consider 'personality' will be explained away as structural and chemical functions of the brain.
Personality is less a finished product than a transitive process. While it has some stable features, it is at the same time continually undergoing change.
I have a lot of different traits to my personality, depending on who I'm around, and what the dynamic in the situation is.
We are all multidimensional and kind of have dual personalities. Everyone puts on different roles depending on what circumstances they're in without even noticing that they do that.
The brain is not a bag of traits. It's startlingly complex. There are few or no single genes with a consistent effect on the mind.
Four personalities are bound to clash.
We do not discuss the anatomical, physiological, and mental characteristics of man considered as an individual; but we are interested in the diversity of these traits in groups of men found in different geographical areas and in different social classes.
I think it's a mistake to try to pin down one particular reason for a person's personality. Don't we all, for many reasons, act differently in different circumstances and with different people?
